Aye yi yi!!
Cheapest way to get stuff here is Parcel Post with USPS. Very cheap, and the service matches. 4-8 weeks delivery.
Justina gave the package to a coworker to ship so didn't see the actual cost until after it was gone. If it is any consolation, you still got these windows for $35 less then we paid Texas Aeroplastics.

Who, by the way, has the cheapest price any where. At least, that is what we were told by the Texas Aeroplastic's representative.
